Boost pedals are one of the lesser known guitar pedals out there. Booster pedals function similarly to overdrive pedals in that they are also designed to push tubes on tube amplifiers to encourage distortion. The other main reason for using these pedals is to create additional volume for solos and pump up your input signal over a long chain with multiple effects.

Treble boosters are also part of the booster family, but they have the unique ability of "boosting" particular frequencies in volume......and you guessed it......frequencies that are typically identified as "treble". This can assist the guitar player in cutting through a live mix, especially.

Most booster pedals (treble, or otherwise), provide boosts in the range of 5 dB to 25 dB and have level (boost amount) and tone controls.
